Large Size Carbon Electrode CNBM China 500--700

Q: What is the striking electrode in the die making? Where is the technical point?: Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.

Q: Why should the carbon brush for the trolley be made of graphite?: What you said is the graphite electrode graphite, there may be a high pure graphite graphite conductive rate so high, strong, high density, the graphite is mostly used in motor vehicles, such as generators, and electric tools.

Q: What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found: The graphite part is called pyrolytic graphite. Stronger than ordinary graphite, strong oxidation resistance.

Q: Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?: Graphite electrodes react with oxygen to form carbon dioxide, soluble in water

Q: What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?: 1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large

Q: Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?: Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%

Q: Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?: Graphite here acts only as an electrode, and the real reaction on the graphite is oxygen, the galvanic cell reaction called iron oxygen corrosion

Q: Carbon graphite electrode and what is the difference?: Graphite electrode is a mixture of natural graphite and petroleum coke and asphalt coke. After being treated by high temperature graphitization, the material is composed of graphite;

Q: Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?: This is not a good estimate of the sheet graphite resistance after 5mm

Q: What do carbon products include?: Carbon and graphite materials are mainly carbon based non-metallic solid materials, in which carbon material is basically composed of non graphitic carbon material, and graphite material is basically composed of graphite carbon material. For the sake of simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials).
